Come on Wouter the A class is back to basics, at a beginner level you can build a fast boat, not world class but really cheap the sails arent dear. With clear decks, low working load, minimum sheets to change its light and super responsive, giving instant feedback on wether youve changed the right thing. Its ideal as a scaled down F12. My 7 year old lad was driving my A class in light wind last weekend, he was tacking, jibing mucking around, we deliberately capsised it and righted it for fun. As for colabsable poles, I reckon they should be an allowable option but not a requirement.
